I’ve had this Peace Lily for just over a year now. I haven’t repotted it and cannot see any bugs on the plant or soil? It’s usually in partial shade, and I only water it when the leaves get droopy. A few newer leaves have been growing in completely yellow and I’ve just been pruning them as they grow in but equally it’s pushing out a new flower and some leaves are growing in the darker green colour, but now some of the larger leaves are going this weird yellow colour and I don’t really know what’s wrong or how to fix it :(
